Are you on the iPhone/iPad format? To my knowledge it is the only aquarium maintenance app on the app store. The dev is a member/sponsor here and has a thread where you can ask questions and make feature requests. That said, it is customizable and should work for anything you need. I just wish there was a sync option between the iPhone, iPad and your pc or Mac.
it does a cloud save every time you open it (at least it does in mine). It has the option for FW and SW. I have all my tanks on this app. There are other apps in the app store, but none of them compare to this one. I love it.
